Torque of Greases

ASTM D1478 - ASTM D4693 - ASTM D4950

ASTM D1478 - Low-temperature Torque of Ball Bearing Grease.

This test method covers the determination of the extent to which a grease retards the rotation of a slow-speed ball bearing by measuring starting and running torques at low temperatures, below -20°C (0°F).

ASTM D4693 - Low-temperature Torque of Grease Lubricated Wheel Bearings.

This test method determines the extent to which a test grease retards the rotation of a specially-manufactured, spring-loaded, automotive-type wheel bearing assembly when subjected to low temperatures. Torque values, calculated from restraining-force determinations, are a measure of the viscous resistance of the grease. This test method was developed with greases giving torques of less than 35 N·m at 40°C.

ASTM D4950 - Classification and Specification of Automotive Service Greases.

This specification covers lubricating greases suitable for the periodic relubrication of chassis systems and wheel bearings of passenger cars, trucks, and other vehicles.
